Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional RTK carrier phase differential technology is used for stakeout, then measurement precision is improved, but operation complexity increases and work efficiency decreases
Solution Approach 1:
The patent creates a virtual copy of the ground surface using depth information and geographic projection to generate a virtual ground surface model. This virtual model allows the system to determine transformation points and calculate paths without physical repeated movements, thereby maintaining precision while improving efficiency
Solution Approach 2:
The patent introduces a ground surface transformation point as an intermediary element between the measured point and the stakeout target. This transformation point serves as a mediator that simplifies the stakeout process by providing a direct path calculation method, reducing the need for repeated equipment movements while maintaining measurement precision
2Measurement precision
If measuring equipment is moved repeatedly to complete stakeout in complex regions, then stakeout accuracy is maintained, but operation difficulty increases and time consumption increases
Solution Approach 1:
The patent performs preliminary actions by acquiring depth information and geographic projection data to create a virtual ground surface model before the actual stakeout operation. This preliminary modeling allows the system to pre-calculate transformation points and optimal paths, eliminating the need for repeated equipment movements during the stakeout process while maintaining accuracy
Solution Approach 2:
By creating a virtual copy of the ground surface with accurate depth and projection information, the system can simulate and plan the stakeout path in advance. This virtual modeling enables single-shot stakeout operations by providing all necessary geometric information beforehand, significantly reducing time consumption compared to traditional repeated movement methods
3Measurement precision
If professional operators are required for complex stakeout tasks, then measurement accuracy is ensured, but labor costs increase and operational complexity increases
Solution Approach 1:
The patent enables the measuring equipment to perform self-service operations by automatically acquiring depth information, generating virtual ground surface models, calculating transformation points, and determining optimal paths without human intervention. This automation maintains measurement accuracy while significantly simplifying operations, allowing non-professional operators to perform complex stakeout tasks
Solution Approach 2:
The patent replaces the mechanical system of repeated physical equipment movements with an information-based system using depth cameras, geographic projection, and virtual modeling. This substitution automates the stakeout process, maintaining precision while eliminating the need for professional operator expertise in complex manual operations
